Typically a relay or resistor. But could be a blower switch or blower motor problem.
93 grand am... that's a Pontiac product. Burn it!
Temp blend door actuator malfunction.
My mom had the same problem and we added freon and it blows very cold all over now.
vacuum line from intake manifold to control unit in dash broken or disconnected
blower motor resistor
the contour has problems with the blower motor switch and the resistor. I would check the resistor connector for signs of melting.
your fuse is blown. car manufacturerers make the dash lights go off when the tail light fuse blows so you know it is blown.
sounds like your water pump ain't pumping, don't drive it till it is!. could be as simple as a new fan bewlt or might even need a pump
the heater blows warm air when fan is on low but blows cold air when fan is turn to higher setting
heater core could be plugged, also check for low coolant
Check your climate control switches, and vaccuum lines. If you have electronic climate control, you probably need to have it serviced. Quite often in Grand Am's 91-2002 have had minor problems with weak linkages within the housing and routing of the climate control rod's and lines.
How do I replace the heating coil in a 2006 Grand Caravan? I have no heat it only blows cold air.
